Contractor Emmanuel Pelekanakis of Demark Corp., Catasauqua, said the 107- foot-tall building will have 1,400 square feet of windows and 92,000 square feet of useable space.

Saunders thanked hospital employees for their cooperation during the construction period. The placement of the large pieces of steel, purchased from Bethlehem Steel Corp., prevented people from parking in many of the adjacent parking spaces for several weeks. Saunders does not expect the remaining construction will involve as many parking spaces.

He expects the project to continue on schedule if the weather is favorable. "We will probably move the first people in after Labor Day as was projected," he said.

The building is almost completely rented, Saunders said. Negotiations involving a couple of small suites are continuing.

Meanwhile, plans and fund-raising for the building's medical auditorium are progressing rapidly. The R.K. Laros Foundation Inc. recently approved a pledge of $100,000 toward the auditorium and the Hospital Aid Society approved a $50,000 donation toward the construction of the auditorium's anteroom and an adjoining conference room.

Dr. Terrill Theman, chairman of the auditorium project, said the physicians have already donated more than $240,000. Donald Heckert, vice president of plant operations, said hospital officials and members of the medical staff met recently and approved the final design concept, the audio- visual systems and the decor.
